A soil sampler having a hollow, ground-contacting drum having a hollow, tapered probe projecting outwardly therefrom for extracting soil plugs. Each soil plug is discharged by gravity into the drum interior. As the drum rotates, all soil plugs are blended with each other. After soil plug collection, the drum is raised and a chute is inserted into the drum. As the drum continues to rotate, the blended soil sample falls from the top of the drum into the chute, slides down the chute and is deposited into a removable cup on a horizontal circular platform of a soil collection carousel assembly. The circular platform is then rotated to bring a new, empty cup into position to receive the next blended sample. The soil sampler is mounted on a trailer drawn by a truck or tractor. All functions are remotely controlled from the cab of the truck or tractor. |
